I wouldn't say this is reinventing the CA system. You don't need to trust any particular browser here. The effect is that web services must offer a secure HTTPS connection, using the existing CA system (or an enterprise CA, if their user base is truly all-enterprise), no matter what browser is being used.

You do need to trust that the particular browser you are using supports preloaded list, and is using the latest updated version of the list, and is not missing any entries!

What you're trusting the browser for there is the extra protection that preloading provides, but that's not the whole benefit here. The larger benefit is that it makes it infeasible for services to neglect to support HTTPS. So, even if your browser's preload list is busted, the site will be guaranteed to support HTTPS because of this effort, which you'll still benefit from.
